MMSZ5V1T1

The MMSZ5V1T1 is a kind of Zener voltage regulator which is available in Pb-free SOD-523 package. It is designed to provide voltage regulation protection and is especially attractive in situations where space is at a premium. Besides, it can be used in applications such as cellular phones, hand held portables and high desity PC boards.

It has some features as follows. (1) small body outline dimensions; (2) low body height; (3) ESD rating of class 3; (4) tight tolerance VZ; (5) steady state power rating of 100 mW.

What comes next is about its maximum ratings. (1): total device dissipation (PD) is 200 mW when TA is 25 and is 1.5 mW/ at derate about 25 ; (2): thermal resistance from junction-to-ambient is 635 /W; (3): storage and junction temperature are both from -65 to 150 . Then is about its electrical characteristics at VF is 0.9 V. (1): Zener voltage ranges from 4.85 V to 5.36 V. (2): test current is 5.0 mA; (3): the maximum capacitance is 225 pF at f is 1 MHz; (4): the maximum reverse leakage current (IR) is 1 A and the maximum reverse voltage is 2 V.
